This sub is only good in the sense that it adds bass to your system. The quality of the bass is a different story. I used REW to see what the sweeps looked like and found that it drops off significantly at 30hz so don't expect any deep rumbles; it peaks way high at 50hz and is full of peaks and nulls throughout the small range in which it does play. The amplification seems like an afterthought, based on the amount of gain needed to achieve an 80dB calibration. The best sub $200 subwoofer is the Polk PSW10; don't jump on the hype train for these Dayton subs.
